IMPROVED MACHINERY FOR FORMING HOOP-SKIRT CLASPS.

Specification forming part of Letters Patent No. 42,608, dated May 3,1864.

To all whom, it may concern:

Be it known that I, FRANKLIN J. TERRELL. of Ansonia, in the county ofNew Haven and State ofConnecticut, have invented a new and usefulImprovement in Machinery for Forming Metallic Articles by Pressure; andI do hereby declare that the following is a full, clear, and exactdescription ot' the same, reference being had to the accompanyingdrawings, forming part ot this specification, in which- Figure lis aside view of a press having my invention applied. Fig. 2 is a verticalseltion ofthe same. Fig. 3 is a horizontal action of the same. Fig. 4 isa longitudinal view of the rotating cylinder which contains the femaleforming-dies.

Similar letters of reference indicate corresponding parts in the severalfigures.

My improvement is more particularly designed for the mannftcture of thevarious kinds of metallic clasps used in the manufactue of hoopskirts,and is attached to the ordinary cutting-out press by which the blanksare cut from the plate.

It consists in the employment, for forming the blanks after they havebeen cut to the required form and have passed through the cutting-die,of a male forming-die made of two or more attached butindependently-movable parts, and a series of rotating femaleformingdies, combined and operating as hereinafter set forth.

A B is the framing of the press, containin g vertical guides for thereception and guidance of the slide C, which carries the cutting-punchD. This framing has in its upper part the bearing for the crank shaft E,whose crank c is connected with the slide C by means of a rod,F,forworking the punch D. These parts are all substantially like thecorresponding parts of cutting and punching presses in common use.

G is the cutting-die, in combination with which the punch D Works,fitted into the upper part of a hollow cast-iron block, H, which isbolted to the bed-plate B. Below the die Gr there is arrangedhorizontally in suitable bearings in the block H the rotating cylinderI, which contains the series of female formingdies b b, of which theremay be any suitable number arranged at equal distances all around thecylinder. These dies are of any form that may be required. The cylinderI derives its rotary motion to present the dies b b succes sively underthe die G, for the reception of the cut blanks, by means of a hookedpawl, c, and ratchet-wheel J, the said' wheel being fast on one end ofthe cylinder and having a number of teeth corresponding with the numberof dies b b, and the said pawl being attached to the punch-slide C andoperating' upon the said wheel to turn the cylinder the requisitedistance every time the said slide rises with the punch after having cutout a blank. y

d e f is the male brmingdie, arranged in a horizontal position oppositeto and perpendicular to the axis of the cylinder I, where it is fittedto slide in suitable guides in block H, for the purpose of operating incombination with the several dies b b, as they are successivelypresented opposite to it by the rotation of the cylinder I. This maleforming-die is composed of three separate pieces arranged one aboveanother, the upper and lower pieces, d and j', being connected rigidlytogether by means of abolt or pin, g, which 'passes through alongitudinal slot, h, in the middle piece, c, and so permits cl and j'to have a limited longitudinal movement independently of e. The pieces dandf are connected with the piece c by a spring, t', which is attachedto a pin,j, secured in the upper piece, d, and to a pin, 7c, secured ina portion of the piece e, which projects beyond the front ends of d andf, and this spring holds back the pieces d and f as far as permitted bythe bolt g, which comes in contact with the rear end of the sloth. Thedie thus constructed has the pin g, connected with one arm ofahorizontally-moving lever, L, which works on a fulcrum-pin, I, securedin the block H, and the other arm ot which is connected by a rod, m,with the lower arm of a lever, K, Which works on a fulcrumpin, n,secured in one side of the framing A B. The upper arm of this lever K iskept in contact with a cam, I), on the crankshaft E by means of aspring, p, applied to its lower arm. This cam is so arranged on thecrankshaft that after the rotary movement of the cylinder I the said camwill, by its action through the lever K on the lever J, cause the latterlever to move the male die t e f toward the cylinder I. During the firstpart of this movement the pieces d, e, and f all move togethcr towardthe opposite female die, b, to commence the bending and formingoperation, and the middle piece, e, coming to a stop at an early stageot' the bending, serves to hold the partly-bent blank in its properposition Wi th respect to the female die, While the independent movementot' the pieces d and j' is continued to complete the bending.

Every time the cutting-punch descends it cuts out a blank and carries itdown through the die G and into one of the dies b of the rotatingcylinder A, after which the punch rises and the cylinder A is rotated bythe paWLand-ratchet Wheel a distance corresponding with the spacing' ofthe dies. Two movements of the cylinder bring` the blank opposite to themale forming-die d e j', and on the blank being brongl'it to thisposition, the advance of the said die which then takes place causes theblank to bc formed into the clasp or other article required. The furtherrotation ot' the cylinder after the retraction of the male forming-diecauses the clasp or other article to be picked ont of the die b by meansof suitablyarranged fingers, (not. shoWn,) which pass between it and thedie, and cause it to drop through an opening, q, in the bed-plate B.

Vhat I claim as my invention7 and desire to secure by Letters Patent,is-

The male formingdie d ef, composed of two or moreindependently-operating pieces, in combination with a series of rotatingfemale forming-dies7 b b, substantially as and for the purpose hereinspecified.

FRANKLIN J. TERRELL.
